Upgrading the software

To upgrade the WANJet appliance to version 4.2.4, complete these tasks:

  • Upgrade the WANJet appliance
  • Activate the license (only required if not previously activated)
  • Save the WANJet appliance chassis serial number (if not previously saved)

Important: For the WANJet appliance to function properly, TCP ports 3703, 3702, 3701, 10000, and 10001 must all be open on a firewall. Any firewalls separating the WANJet appliances must have these ports open. For specific information about configuring ports, refer to the WANJet Appliance Administrator Guide.

Important: Version 4.0 introduced a new licensing procedure. If you are upgrading from version 3.1.x, you must first obtain a Base Registration Key. Do not proceed with the upgrade until you have the Base Registration Key. If you did not receive an email with a Base Registration Key, contact F5 Networks Technical Support (and be sure to have the WANJet appliance serial number) before attempting to install the software upgrade.

To upgrade the WANJet appliance

  1. Log in to the WANJet Web UI, by typing the following address into a browser's Address line.

    https://<WANJet IP address>:10000

  2. Verify that a disk image of the new version of the WANJet software is accessible from the local computer on which you are viewing the WANJet Web UI (on CD-ROM, for example).

  • Switch the operational mode of all WANJet appliances to Inactive.

  • Upgrade all of the WANJet appliances.

  • One at a time, change the operational mode of each WANJet appliance to Active.

To activate the license

Note: You need to perform this procedure only if you have not previously activated the WANJet appliance license.

  1. In a web browser, access the Web UI using HTTPS and port 10000.
    For example, if the IP address of the appliance is, type in the web browser.
    The welcome screen opens.

  2. Type the user name and password.
    The default user name is admin and the default password is admin.

  3. Click the Log On button.
    The WANJet Status screen opens.

  7. Click Next.
    The EULA (End User License Agreement) screen opens.

  8. Read the EULA, and then click Accept if you agree to the conditions.
    When license activation is complete, the WANJet License Details screen opens and shows the current license date.

New features and fixes in this release

This release includes the following new features and fixes.

New features

WANJet 500 Platform
This release includes support for the WANJet 500 platform. This platform is Restriction of Hazardous Substances (RoHS) compliant and meets RoHS guidelines regarding lead-free electronic equipment. Documentation specific to this platform includes the F5 WANJet 500 Appliance Quick Start Card and the Platform Guide: WANJet 500, which are posted on AskF5.

WANJet Appliance Administrator Guide
The WANJet appliance Web UI now links to the updated WANJet Appliance Administrator Guide, formerly the WANJet User Guide. The update contains more deployment information on one-arm configuration, redundancy, and high-availability, and it describes new options available in the Web UI, such as Fail to Wire and Fail Close, Web update, SNMP IP address type, and using the roadmin account. In the Web UI, click the User Manual link to open the PDF.

Fixes in this release

This release includes the following fixes.

WANJet appliance private MIB file (CR64597)
Previous releases did not include the WANJet appliance private MIB file. You use this file with SNMP-compliant software to browse the MIB. You can now download this file using the Web UI. In the navigation pane, expand Configuration and click Monitoring. On the WANJet Syslog and SNMP screen that opens, click WANJet Private MIB to download the file.

Configuration options for network interface cards (CR68048)
We have removed the 1000BaseT Full-Duplex media type option for configuring the eth0 (LAN) and eth2 (WAN) interface cards. You should use Auto Negotiate instead as the media type for high speeds. The upgrade of the WANJet appliance changes instances of the 1000BaseT Full-Duplex media type for eth0 and eth2 to Auto Negotiate.

Known issues

The following items are known issues in the current release.

Passthrough sessions (CR60178)
After a high volume of traffic passes through the WANJet appliance, the dashboard may temporarily display more passthrough sessions than are actually occurring.

Real Time Traffic report (CR61437)
The amount of network traffic shown in the Real Time Traffic report appears to repeatedly spike to twice the actual amount, in 30-second intervals.

SSL encryption implementation (CR64020)
SSL encryption is currently implemented only for optimized TCP traffic. In future releases, we plan to support TCP and UDP protocols for SSL encryption.

VLAN traffic and LAN router value configuration (CR64021)
If you want to process VLAN traffic, do not configure a LAN router value in the Local WANJet link of the Web UI.

GRE packets captured by tcpdump (CR64731)
When the tcpdump diagnostic tool captures Generic Routing Encapsulation (GRE) packets on the WANJet appliance, it does not decode the packets correctly.

Application QoS bandwidth (CR64742)
For an Application QoS Policy, setting the Link Bandwidth to 128 Kb/s or less may reduce FTP download speed.

TDR-2 efficiency impacted by slow servers (CR65171)
TDR-2 efficiency is degraded when transmitting data from low-performance servers.

WANJet 200 crossover cable (CR65989)
The WANJet 200 previously included an orange CAT6 crossover cable to connect the WANJet 200 to the WAN. We have replaced the orange crossover cable with a new yellow crossover cable that is RoHS compliant. The WANJet 200 Appliance Quick Start Card packed in the shipping box may still refer to the cable as an orange cable. Refer to the updated document posted on AskF5.

End-user diagnostics boot menu option (CR68894, CR68895, CR68896)
The WANJet appliance includes a boot menu option, EUD (end-user diagnostics), as of version 4.2.4. You see this option on the serial console (if one is connected) when starting a WANJet appliance. The EUD option works only on WANJet 500 appliances, and is not supported on WANJet 200 and 400 appliances. If you run the EUD option on the WANJet 500, the diagnostics includes the following inaccurate information:

  • The EUD reports that the WANJet 500 has two hard drives when it has only one hard drive.
  • The EUD reports that the WANJet 500 has two CPUs when it has only one processor.
  • The EUD reports the WANJet 500 platform ID as D41 when it should be D100.
